The key factors are: the amount of content, enabled features, deployed service applications, number of farms, and availability requirements. We recommend that web servers and application servers have two network adapters: one network adapter to handle user traffic and the other to handle communication with the servers that are running SQL Server. IOPS requirements for content databases vary significantly based on how your environment is being used, available disk space, and the number of servers that you have. For example, if you have a RAID 1 system that has two physical disks, and your counters are at the values that are shown in the following table. While not providing a complete picture, combining latency, IOPS and throughput measurements can help gauge performance. As said caching plus things like lengthy sequential reads depends on your workload could account for this - we often see "impossible" numbers like 12, IOPS on a 12x 15K disk shelf. Recycle bins Until a document is fully deleted from both the first stage and second stage recycle bin, it occupies space in a content database. Let's dig the subject and understand it though one more better illustration.
Rotational speed (aka spindle speed). Average latency.
Average seek time.
Demand and expert opinion Queue Depth. Calculate the number of drives needed to satisfy the IO requirements Example values:. I've attached a CSV with the perfmon data and my calculations as specified in my original post if anyone wants to take a look at it. In the previous blog entry, i had shown sql which allows you to get the iops during peak hours. Average Latch Wait Time ms This counter shows the average latch wait time for latch requests that had to wait.
So, this sample drive can support about IOPS.

We do not recommend a wide area network WAN topology in which a server that is running SQL Server is deployed remotely from other components of the farm over a network that has latency greater than 1 ms.
Planning your next buildout and thinking SSDs are still far in the future? We found 10 helpful replies in similar discussions:. If you are deploying services that require fast data then you might need to use shared SSD storage for your data disks, and this is made possible using a Premium Storage Account with DS-Series or GS-Series virtual machines.
Sequential operations will always be less intensive than random operations, and reads are always less intensive than writes.
